Charlie,
I retract my earlier statement upon receipt of new information.
Here is what is printed on the PLA's for the CBM high profile systems
that I have:
906114-04
CBM2 LP 4 PLA
HIGH BOY
(known to work with the 8088 co-processor in a B700 prototype)
906114-05
HIGH BOY
62E5
(found in 3 CBM 256-80 systems; 2 with and one without with the 8088
co-processor)
Given the evidence the 906114-05 will work in the non 8088 CBM 256-80
and this is the PLA you want. I do not have any systems with the -01,
I was mistaken. Thus I can't say that the -01 will help you.
Bill
